When two electric charges, q 1 q 1 ​ q, start subscript, 1, end subscript and q 2 q 2 ​ q, start subscript, 2, end subscript are held a distance apart, the electrostatic force between them is F E F E ​ F, start subscript, E, end subscript. The charge of q 1 q 1 ​ q, start subscript, 1, end subscript is then doubled.

Unpolarized light of intensity i_0=750w/m^2 is incident upon two polarizers. after passing through both polarizers the intensity is i_2=280w/m^2. (a) what is the intensity of the light after it passes through the first polarizer in w/m^2? (b) write an equation for the angle between the polarizers in terms of the initial (i_0) and final (i_2) intensities. (c) find the angle between the polarizers in degrees.

The graph represents the distance a car travels over time while on the highway. which statement about the car's trip is accurate? a) the car does not move over time. b) the car travels at a constant velocity. c) the car's velocity increases constantly over time. d) the car's velocity decreases constantly over time.
